WHEEL Filed 001:. 14. 1927 Patented Nov. 11, 1936 UNITED STATES cmusrmn J. HUG, F HIGHLAND, ILLINOIS- WHEEL Application filed October 14, 1927. Serial No. 226,061. I

My invention relates to improvements in wheels and consists of a spider type of wheel, having a cast hub provided with a peripheral flange arranged to detachably receive the spi- 6 der member and brake-drum; the tire rim being mounted upon a spider member by means including a sufficient number of wedge-members to permit the ready withdrawal of the rim from the wheel by the removal of a sufficient number of said wedges. Such detachable mounting of said rims is effected by a pinion mounted in the spokes of the spider member, and wedge members, each provided with a rack, which are carried to and held in place by said pinions when the wheel is in assembled condition.

By the described structure I attain simplicity of operation, the simple and speedy removal of four of the wedge members usually serving to dismantle the wheel. I also accomplish the accurate alinement and balancing of the tire rim with reference to the hub. In addition to these advantages I also secure economy in manufacture and lightness in weight.

My invention is equally applicable to either single-tire or dual-tire wheels.

Description As shown in the drawings, I employ a hub A having a peripheral flange 3 for the removable mounting of the spider'member 4 and the cupped brake drum 5; thesemembers bein detachably secured together by means of bolts 6. Four or more spokes 7 of the spider member 4 are suitably beveled as indicated at 8, to slidingly receive the wedges 10, the wedges being arranged as shown in Fig. 1; their adjustment being secured by means of the pinion 9 mounted on the pin the wheel.

11 and engaging the rack 12 with which the H base of each of the wedges 10 is provided.

The outer faces of the wedge-members '10 are suitably grooved to receive one or two tire. rims C, said rims C being of usual and standard construction.

The pins 11 are mounted through the spokes 7 as shown in Fig. 2, and each pin 11 is provided with a polygonal head 13 which may be rotated by any suitable tool, such as a cupped key or a wrench.

The wedges 10 are arranged in alinement with the plane of the rim C, and in oppositely directed pairs as shown in Fig. 1.

7 Mode of operation When it is desired to remove the tire or tires D, the pin 11 is rotated to unseat the wedge 10 wherewith its pinion 9 is engaged. A sufiicient number of the wedges 10 being thus unseated, the rim member C with the tire or tires Dmounted thereon is entirely removed from the spider member 4:. The new tire or tires may then be mounted upon the rim or rims O in the usual manner, the rim C placed in position, thewedge members 10 slid into position'upon the spider member 4: and then looked in position by means of the rack 12 and pinion 9.

- Saidwedge members,'as shown, are adjustable in alinement with the periphery of Variations of the described and illustrated structure may be made a without departure from my actual invention as defined'in the appended claim.

I'claim: p An improvement in wheels of the demountable rim type, comprising a spider carried on the hub and having a plurality. of spokes,

formed wedge shaped circumferentially of posite direction to the intervening wedge 90. certain of the spokes having theirouter ends shaped ends, Wedge shaped members carry- ,ing the tire rim and seated on the Wedge shaped ends of'the spokes, the face of the wedge shaped members facing the spokes formed with racks, and a pinion carried by 1 fixed my signature. k w
